摘要： A method, system and computer program product for generating answers to questions. In one embodiment, the method comprises receiving a query, conducting a search through one or more data sources to identify candidate answers to the query, and providing each of the candidate answers with a preliminary score. The method further comprises filtering out any of the candidate answers with a preliminary score that does not satisfy a defined condition. The candidate answers having preliminary scores that satisfy this condition form a subset of the candidate answers. Each of the candidate answers in this subset is processed to produce further scores. A ranking function is applied to these further scores to determine a ranking for each of the candidate answers in the subset; and after this ranking function is applied, one or more of the candidate answers are selected as one or more final answers to the query.

摘要： A method facilitates generating a number of candidate passages from a corpus that answer an input query, and finds the correct resulting answer by collecting supporting evidence from multiple passages. By analyzing all retrieved passages and that passage's metadata in parallel, an output plurality of data structures including candidate answers based upon the analyzing is generated. Then, by each of a plurality of parallel operating modules, supporting passage retrieval operations are performed upon the set of candidate answers, and for each candidate answer, the data corpus is traversed to find those passages having candidate answer in addition to query terms. All candidate answers are automatically scored causing the supporting passages by a plurality of scoring modules, each producing a module score that is processed to determine one or more query answers. A query response is then generated for delivery to a user based on the one or more query answers.
摘要翻译：一种方法便于从语料库中产生一些候选段落来回答输入查询，并通过从多个段落收集支持证据来找到正确的结果。通过并行地分析所有检索到的段落和该段落的元数据，生成包括基于分析的候选答案的输出多个数据结构。然后，通过多个并行操作模块中的每一个，对候选答案集执行支持通道检索操作，并且对于每个候选答案，遍历数据语料库以找到除查询词之外的具有候选答案的段落。所有候选答案被自动计分，由多个评分模块引起支持通道，每个评分模块产生处理以确定一个或多个查询答案的模块分数。然后基于一个或多个查询答案生成用于传递给用户的查询响应。

摘要： Diffusing evidence among candidate answers during question answering may identify a relationship between a first candidate answer and a second candidate answer, wherein the candidate answers are generated by a question-answering computer process, the candidate answers have associated supporting evidence, and the candidate answers have associated confidence scores. All or some of the evidence may be transferred from the first candidate answer to the second candidate answer based on the identified relationship. A new confidence score may be computed for the second candidate answer based on the transferred evidence.
摘要翻译：在问题回答期间候选答案之间的扩散证据可以识别第一候选答案和第二候选答案之间的关系，其中候选答案由问答电脑程序产生，候选答案具有相关的支持证据，候选答案具有相关的信心分数。基于所识别的关系，所有或一些证据可以从第一候选答案转移到第二候选答案。可以基于转移的证据为第二候选答案计算新的置信度。

摘要： Evidence profiling, in one aspect, may receive a candidate answer and supporting pieces of evidence. An evidence profile may be generated, the evidence profile communicating a degree to which the evidence supports the candidate answer as being correct. The evidence profile may provide dimensions of evidence, and each dimension may support or refute the candidate answer as being correct.
